I used to live in Boise and every once in a while I check to see what shops are there thinking I might drive over and see friends. In four years I have not seen enough shops to make the trip worthwhile
There are fast food, banking and grocery shops, but not much. Gas station audits used to bring me ~$100 a week, but I’m not seeing those either.
Sal Lake City, a four hour drive south, has a lot of shops. Portland is about five hours west. Both could make decent overnight or weekend trips.
Boise was an emerging market at the turn of the central, but it never really developed. It is no longer a market that many businesses test advertising or products in. Many large brands have had to close shop in the area because the local economy is still depressed.
Consider that the area has seen constant development for the last two decades and it still only has one mall.
